UNITED STATES CLARENCE E SACRE, OF ST. LOUIS, MISSOURI.

PISTON-RING CLOSER.

Application filed August 22, 1923.

T 0 all whom it may concern:

Be it known that I, CLARENCE E. Enema. a citizen of the United States. residing at St. Louis. in the itate of Missouri. have invented certain new and useful Improvements in Piston-Ring Closers. of which the following is a specifi ation containing a full. clear. and exact description, reference being had to the accompanying drawing. forming a part hereof.

The invention consists in the novel construction and combination of parts hereinafter particularly described and distinctly claimed.

The object of my invention is to provide an improved tool for use in closing: or com-- pressing: split piston rings in the piston- ;grooves. so that the piston may be placed in the cylinder (with the compressed rings in place) very quickly. and with the ex,- penditnre of very little time or labor; and which tool shall be of simple construction. durable. and of low cost. as well as highly efficient.

In the drawings.

Fig". 1 is a top plan-view of my pistonring! closer in its present form. as used in connection with a common piston. and

Fig. 2 is an edge-view of the same.

The numeral 1 designates one of a pair of handles. and 2 the other handle of the pair. which are connected by a pivot 3. in a manner similar to that used in pivoting the blades of shears or scissors. so that when said handles are separated or moved in a given direction. say at the handle-ends. the jaws having: holes 4 and angular-slots 5. will he correspondingly located.

A circular clamping-hand 6 is provided with a perforation. 7 near one of its ends. which is slipped into and through its said inclined or angular-slot 5. and is moved therein towards and into the adjacent perforation 7. the construction being such that the said end of said band will be thereby pivotally-connected to one of the slotted and perforated portions of one of said handles, by a sort of hook-construction. which permits the parts to be readily assembled and disconnected.

The said pivot 3 should be located comparatively near the slotted ends of said handles 1 and 2. so that suflicient leverage will be provided. for compressing the piston-rings. as well as the said band 6 it self, and in the present case I have located Serial No. 658,713.

said pivot at a point about one-fourth the length of said handles.

The said band 6 is preferably made of spring-steel. of sufficient width to cover and compress three adjacent piston-rings if same are of small size. and said band is curved into circular form. having :1 normal diameter that is considerably in excess of the diameter of the uncompressed or open piston-rings.

A short attaching-flap 8 is preferably made of the same material as that of which said band 6 is composed. and has one of its ends secured or fixed by means of a suitable rivet 9 to the curved exterior of said band. at a point adjacent the free end of the latter. and the opposite end of said flap is provided with a suitable perforation 7. that is like or similar to the perforation in the handle-end of said band. Fig. 2. and the said perforated end of said flap is slipped into and through the inclined-slot of the handle-jaw that is opposite that to which said band is pivoted. and is moved in its slot towards and into the adjacent perforation of the flap handledaw; thereby pivotally attaching the perforated end of said flap to said flap handle-jaw.

The curved free end-portion 10 of the said clamping-hand 6 is arranged to overlap and slide upon the adjacent curved inner surface of said hand. in closing around the piston 11. and the piston-ring or rings 12.

The operation.

The normal relative positions of the handles 1 and 2. as well as of the clampingband 6. are those in which they are shown in Fig. 1.

In placing piston-rings in the piston 11. the operator first places the expanded rings in the grooves of the piston. in the usual manner. and then places the clamping-band 6 around the said uncompressed rings. or a single ring if desired. and then closes the said band firmly upon the rings, by grasping the handle-portions of said handles 1 and 2. and brings the parts to the positions in which they are shown in solid lines in Fig. 1; whereupon the said piston-rings will be properly closed. and the piston carryinc; them may be quickly slipped into its cylinder.

I I do not limit myself to the particular material which I have mentioned, as the materigil belohfinged, a bfl the size and form of the inemhei' s, without departing from the scope of my claims.

I claim l. A tool for closing piston-rings, composed of crossed pivoted handles, a clamping-band having one of its ends pivotally connected to one of said handles, and its opposite and arranged to slide in engagement with the inner surface of said band, in closing piston-rings, and a flap having one end fixed to' the outer surface of said band at a point near the sliding end thereof, and having its opposite end pivotally secured to the companion handle.

2. A; tool for closing piston-rings, composed of crossed pivoted handles having inclined slots and perforations near their adjacent jaw-ends, a clamping-hand having a perforation at one end that is pivotallyengaged by the slotted and perforated portion of one of said handle jaw-ends the opposite end-portion of said band being curved, and adapted'to slide in contact with the inner surface of the band in closing piston-rings; and a flap having one of its ends secured to the outer surface of said hand at a point near the said sliding-end thereof, and having a perforation at the end that is opposite its band-end, in which perforation said slotted and perforated portion of the companion handle jaw-end is pivotally located.

In testimony whereof, I have signed my name to this specification in presence of two subscribing witnesses? CLARENCE E. SACRE.
